1/10 is left.
Explanation:
First we need to find a common denominator. Since 5×2=10, if we multiply 4/5 by 2/2, we will be able to subtract that from 9/10.
4/5×2/2= 8/10. Then if we subtract that from the 9/10 left of the pizza, we get 1/10, the amount remaining.
Hope this helps :)

Answer:
<u>19.17 feet</u> of lace will be leftover.
Step-by-step explanation:
Given:
Kaitlyn is making a quilt she purchased a 46 feet long piece of lace to sew around the edges of the quilt she needs 322 inches of lace for the quilt.
Now, to find the feet of lace will be leftover.
<u><em>Total feet of lace =</em></u> <u>46</u>.
Kaitlyn needs lace for the quilt = 322 inches.
So, by using conversion factor we change inches into feet:
12 inches = 1 foot.
322 inches = 
<u><em>Feet of lace she need for the quilt =</em></u> <u>26.83</u>.
Now, to get the feet of leftover lace:
<u><em>Total feet of lace - feet of lace she need for the quilt</em></u>


Therefore, 19.17 feet of lace will be leftover.

Answer:
Step 2.
Step-by-step explanation:
When you have a coefficient on a side of the equation that you need to get rid of, you must divide by the number. For example, in the problem:
3(x+8)² = 75
Here, you need to divide both sides by '3' instead of multiplying, which was done instead. Then you get:
(x+8)² = 25.
Therefore, his mistake was made at Step 2.
